This-invention :relates to: a "device- *for" stripping cards from thecard cylinder of the jacquardmechanism of aloom..

The principalobject of the invention is to construct the card stripper in such a manner that T the cylinder may be readily removed from the loom for repairs, etc., withoutdis-; :turbing the general relation existing between the cylinder and the stripper, after :the stripper has oncebeen properly adjusted with respect atO the cylinder, so thatthe cylinder: may be replaced in the'loom and immediately placed in operation without requiring any. additional adjustment between a the. cylinder and-the card stripper. r r a j The detail construction and 'operationot thede'vice will be' fully disclosed hereinafter, reference being had to the accompanying drawings, of which: Y

'InFigs. 1 and 2, Ihave shownsufiicient of an ordinary jacquard mechanism to illustrate-the application of my invention thereto. This mechanism comprises usual horizon any disposed and axially reciprocable rods'l, located at each end of the card cylinder. 2, the two rods beingfadapted jointlyto support and reciprocate the card cylinderlater- :Thye-psecuring bolt 23% provided with azhead ally, in ;a horizontal plane, so that the string of cards carried by the cylinder will be brought successively into co-operating relation with the 'needles (not shown) of the jacquard mechanism.
